This is a discussion on iridium plugs within the General Maintenance, Troubleshooting & Accidents. forums, part of the Tech & Modifying & General Repairs category; how much for these plugs and where do i find them ,.....how much hp do you get...

I wouldn't waste your money. I measured no power gains when I dyno tested them on a full out street Honda motor. On top of that I have experienced breakage problems, so I just use platinum plugs now exclusively. Work like a charm, no problems. BTW, your stock ones are platinum so don't bother changing them unless you're running high boost ona big turbo.

if im not mistaken arent there a set in the vishnu stage 0 kit.....the reason im asking is the whole warranty issue.....i want to mod but the last thing i need is to fight the soa.....just have the axel back from prodrive, might go vishnu...who knows....i would like up/dn pipe from godspeed......but time & $$$$ are the issues.....maybe ebc ??????

from what i know, the iridiums won't do much unless you have upgraded performance parts. like more boost, fuel, etc. with a UTEC, where you can mess with the timing, the iridiums will really help (as i was told).

i currently have the Denso iridiums and have noticed nothing significant, but then again, i haven't dynoed my car nor have i added much of anything except for an MBC.
